If LeBron James starts at center in Game 4, it would be his first game at that position in his NBA career. Playing inside may help his scoring, especially in the paint. James is attempting less than 45 percent of his shots in the paint in this series, after attempting nearly 65 percent of his field goals in the paint in the 2012 Finals.

Mike Miller is starting tonight to help jump start the Heat offense.
Where he might struggle is on the defensive end. On Tuesday Gary Neal made 3 1st half 3-pointers with Mike Miller as the primary defender (4 if you want to count the fact Miller let Neal leak out for a transition buzzer beater 3).
Also Miller was bad on a lot of defensive rotations. One of the factors may be he's only played 75 minutes with the Chalmers/Wade/James/Bosh lineup including the postseason and regular season.
Udonis Haslem, Shane Battier and Norris Cole all played more minutes with that 4 man lineup this season.

LeBron has attempted his shots from further away and is drawing fewer fouls per game against the Spurs in the 2013 Finals than he did against them in the 2007 Finals with the Cavaliers.

This is the 1st time since acquiring LeBron James and Chris Bosh that the Heat will have played at least 10 games without winning 2 in a row (Game 5 vs Bulls-Game 1 vs Pacers).
Miami has not played that many games without winning 2 straight in MORE THAN 4 YEARS, since a 16-game span in Jan.-March 2009.
